Black Box Fiber Optic A/B Switch Latching - switch

There's a reason why these types of manual switches continue to be the switches of choice for networking professionals everywhere: the tried-and-true optical switches perform as promised year after year. They're reliable because they use micro-mirrors instead of electronics to route data signals from one fiber optic port to the next. And unlike conventional electronic switches, there are no complex and vulnerable electronic circuits to monitor and protect from intrusion, component failure, or interference.
